UNITED STATES OLIVER S. BO'WMAN. OF COLORADO SPRINGS, COLORADO.

WINDOW.

Application filed January 3, 1924. Serial No. 684,221.

To all whom it may concern:

Be it known that I, OLIVER S. BOWMAN, a citizen of the United States, and a resident of Colorado Springs, in the county of El Paso and State of Colorado, have invented a new and useful Window, of which the following is a specification.

My invention relates to windows of the rocking type and has for its object the provision of a window of this type having sashes which are adjustable, lockable and removable. Other objects will appear as the description progresses.

Figure 1 represents a front elevation of my window with both sashes closed; Fig. 2, an elevation of a section on the line AB of Fig. 1; Fig. 3, a plan view of a section on the line C-D of Fig. 1; Fig. 4, a side and an end elevation of the screws 14 and 15 in their cooperative positions, drawn to an enlarged scale (as are the remaining Figures); Fig. 5, a side and an end elevation of the screw 15; Fig. 6, two side elevations of the screw 14; F 7 side elevations of the screws 4 and 6; Fig. 8, a fragmentary sectional elevation showing the manner of mounting the lower sash 5; Fig. 9, an elevation of a section on the line E -F of Fig. 8; Fig. 10, an end and a side elevation of the plate 10; Fig. 11, a fragmentary sectional view showing the manner of mounting screws 14 and 15; Fig. 12, a fragmentary sectional plan view showing the manner in which the thumb screw 12 engages the depressions in the plate 10.

The invention comprises a window frame 1, having a sill 2 with a rectangular ridge 3, and screws 4, with convex ends, screwed into said sill; a lower sash 5 having screws 6, with concave ends, screwed into the bottom of its lower rail mounted on the convex ends of screws 4 in the manner shown in Figs. 8 and 9; plates 10, with dep=ressions 11, l'IlJOltlSGd in the jambs of said frame as shown in Figs. 1, 2, 3 and 12; thumb screws 12 screwed thru. the side rails of said sash 5 and into the concave depressions 11 of plate 10, as shown in Fig. 12; an upper sash 13 having screws 14, with tongued ends 14 screwed into the bottom of its lower rail and mounted on screws 15, having bifurcated ends 15, screwed into the jambs of said frame, as shown in detail in Fig. 11; plates 10, similar to plates 10, mortised in said jambs; thumb screws 12, similar to thumb screws 12, screwed thru the side rails of sash 13 in the same manner as shown in Fig. 12; stops 16, hav ing triangular beads 16, mounted on said jambs.

When the sashes are closed, the triangular beads 16" fit into longitudinal V grooves in the side rails of b oth sashes, and the flange 17 fits in front of the rectangular ridge 3, and thereby prevents wind, rain or dust from passing between the side rails and the jambs, or the bottom rail of the lower sash and the sill of said frame.

The lower-sash 5 may be adjusted in its relation to the upper sash 13 and trued in its relation to the jambs by means of screws 4 and 5, which also form hinges upon which the low-er sash rocks.

The upper sash 13 may be adjusted vertically and horizontally by means of screws 14 and 15, respectively, which also form the hinges upon which said upper sash rocks.

The sashes are locked at any angle, by screwing thumb screws 12 and 12 until the convex ends enter the concave depressions 11 in plates 10. For convenience, the thumb screws thru the right hand side rails are threaded right hand and those thru the left hand rail are threaded left hand.

The construction of the screws 4 and 6, and of the screws 14 and 15 permits the sashes to be removed.

I claim:
